Of this amount, 54 percent was buried and 13 percent was combusted. Energy can be recovered from burying or burning waste. Communities across the U.S. are looking at ways to maximize resource and energy conservation in response to EPA’s Resource Conservation Challenge.

To provide some answers to that question, air quality specialists in EPA’s Office of Research and Development (ORD) are gathering data to quantify the extent and concentrations of selected motor vehicle emissions near heavy-traffic roadways. The data will be useful in the development of programs, such as road and barrier construction, that could minimize near-road exposures to high-risk pollutants.

In that time, EPA researchers have identified hundreds of potential contaminants to drinking water quality. To help stakeholders navigate this body of information, EPA recently commissioned a new online tool, the Drinking Water Treatability Database, that provides information on controlling these contaminants in drinking water.

Riparian buffers – vegetated regions adjacent to streams and wetlands – are a common means of intercepting and controlling these pollutants as they enter water bodies. EPA considers nitrogen one of the top stressors to aquatic ecosystem health. To determine how to better protect these environments from excess nitrogen, National Risk Management Research Laboratory's (NRMRL’s) Ground Water and Ecosystems Restoration Division (GWERD) conducted a comprehensive review of riparian buffer practices.

Aquifers act as filters that smooth out short-term climate fluctuations and record continental climate signals. Past temperature signals (paleotemperatures) are stored with dissolved noble (inert) gases in ground water. Using noble gases as proxies, NRMRL hydrologists are sampling paleotemperatures in the Elwha watershed on the Olympic Peninsula in Washington State.
